Robust Algorithm for Fitting Sphere to 3D Point Clouds in Terrestrial Laser Scanning
Laser scanning Fitting Terrestrial photogrammetry
2015/12/16
Sphere target is one of the most important tools in terrestrial laser scanning. Different point clouds obtained form different views can
be transformed into the same coordinate system frame by using ...
REPRESENTATION OF GRADIENTS OF A SCALAR FIELD ON THE SPHERE USING A 2D FOURIER EXPRESSION
2D Fourier series gradients representation coefficients D-functions spectral transfers
2016/1/18
Representation of data on the sphere is conventionally done using spherical harmonics. Making use of the Fourier series of the Legendre function in the SH representation results in a 2D Fourier expres...
Robust and Automatic Vanishing Points Detection with Their Uncertainties from a Single Uncalibrated Image, by Planes Extraction on the Unit Sphere
Photogrammetry Geometry Vanishing points extraction Image Orientation Error estimation
2015/12/4
This paper deals with the retrieval of vanishing points in uncalibrated images. Many authors did work on that subject in the computer vision field because the vanishing point represents a major inform...
Symmetric quadrature rules for simplexes based on sphere close packed lattice arrangements
Quadrature Integration Symmetric Triangle
2015/7/3
There have been significant efforts to identify high-order quadrature rules on d-simplex and d-hypercube geometries as evidenced by the surveys in [1–5]. On thed-hypercube, it is well-known that optim...

2014/4/21
The global spatial grid is an important spatial data model for Digital Earth. Discrete Global Grid provides a means of rasterizing the
earth surface, and then has been considered as the basic data m...
Finding Optimal Allocation of Constrained Cloud Capacity Using Hyperbolic Voronoi Diagrams on the Sphere
Cloud Computing Voronoi Diagram Voronoi Diagram on the Sphere
2013/1/28
We consider a network of computer data centers on the earth surface delivering computing as a service to a big number of users. The problem is to assign users to data centers to minimize the total com...

Numerically exact calculation electromagnetic heat transfer between dielectric sphere plate
2015/8/10
We present a numerically exact calculation of electromagnetic heat transfer between a dielectric sphere and plate. We compare the calculation to a recent experiment. Our calculations unify various app...
Black Holes as Incompressible Fluids on the Sphere

2011/9/14
We consider finite deformations of the p + 2-dimensional Schwarzschild geometry which obey the vacuum Einstein equation, preserve the mean curvature and induced conformal metric on a sphere a distance...
Drag force on a sphere moving towards an anisotropic super-hydrophobic plane
Drag force sphere super-hydrophobic
2011/8/26
We analyze theoretically a high-speed drainage of liquid films squeezed between a hydrophilic sphere and a textured super-hydrophobic plane, that contains trapped gas bubbles. A superhydrophobic wall ...
Drag on a fluid sphere embedded in a porous medium
Brinkman equation Modified Bessel functions Drag force
2010/9/26
The problem of the Stokes flow past a fluid sphere embedded in a porous medium is studied. The Brinkman equation for the flow outside the fluid sphere and the Stokes equation for inside the fluid sphe...
Two dimensional curved disks on a sphere: the evolution of kinetic energy
curved space kinetic energy
2010/9/27
We put disks on a sphere between two parallels of this sphere. The disks have the curvature of the sphere and interact via a simplified Hertz law. We analyze the behavior of the total kinetic energy o...
